New rig, doesnt get display sometimes.

post #1 of 7
Thread Starter 
Well sometimes when I start up, i don't get a display. Its probably a 10% chance.

The fans and everything kick on and I think it even loads windows, but theres no display. Turning it off and back on fixes it. But its annoying.

What could cause this?

All hardware in my computer is brand new.

The 680i underclocked my quad core to 1.8ghz (should of been 2.66) and my ram to 5-5-5-18 with 1.9v (should be 4-4-4-12 with 2.1v)

Which makes me believe the motherboard has set a voltage or something else wrong, and its causing this.

Any ideas?

This is known to happen with 680i boards. Just part of their "charm". Dont worry about the underclocking thing. Sometimes when the cmos is reset it sets the CPU clocks to lower then stock, it does this with my X6800 often. Just bump all the voltages back up as well as the FSB and you will be ok (or the multi... i forget which one it lowers). Anyways, I am assuming you are seeing this problem when you attempt to overclock? If so this is normal. The 680i has the safe bios feature or w/e its called that will reset the bios settings when the user attempts an OC that is not stable enough to start the Post. Sometimes when this is activated upon reset the monitor will not pick up a single... this also happens frequently when I overclock. If that is what you are seeing then it is completely normal. However, if you are not receiving a signal upon cold boot then you might have a problem elsewhere. Question, how are you running your am at your overclocked settings? Are you using the independent ram frequency or are you using sync 1:1?

This happens on stock also. It happened on the default bios, and even when my processor was underclocked to 1.8.

I'm not much of a overclocker. My CPU is at 3.2ghz by upping the multi twice.

I'm not even sure how to get 1:1, so i'm not messing with it.

Nothing else is OCed but my processor, and this happens at 2.66ghz also. I'm thinking one piece of my hardware is faulty.

When the monitor does not receive display, upon restart do you notice anything odd, for example, are your bios settings reset? Do you see the lowered clocks on your QX6700 (below stock) only upon rebooting from the lack of display monitor problem?

It could even be that your dvi/vga cable is dodgy, try using a different one

Its starts normal the next boot.

I just saw the board was setting my CPU voltage to v1.4, when it should be v1.35. So I set it manually, and it boots fine.

Also, this board is setting my 2x1GB Corsair ram to 2t, and they are in the dimm 0 and 1 slots (the blues)... Forcing 1T = memory errors.

Why?

First off, never use auto, always use manual, that will solve a multitude of problems right there. As for the timing issue.

Some ram just doesnt like running 1T. Assuming you havent messed with the memory settings, your ram is running independent from the FSB at a speed of 800mhz. Forcing 1T on a ram that is made to spec at 2T will cause errors without extra voltage. My suggestions would be to run your ram in sync with your FSB at 1:1. This will run your ram at a lower mhz, but will allow you to use tighter timings. There is really no performance increase to be had by running your ram in async.

If you need any help doing this just post and Ill get on my computer and walk you through it. Hopefully you have msn messenger or something!
